Fix output image consistency issue

[takahirom]

It seems that the task information provided by TestTaskSkipEventsServiceProvider, which is necessary to decide whether we should restore the cache to the output directory, isn't saved correctly. Therefore, I removed TestTaskSkipEventsServiceProvider and now always restore the cache. The performance impact appears to be minimal, and consistency is more important.

The reason why the test fails is that when the test fails, testTask.doLast{} is not executed, so intermediateDir is not updated.

  @Test
  fun verifyAndRecord_changeDetect() {
    RoborazziGradleProject(testProjectDir).apply {
      record()
      val recordFileHash1 = getFileHash("$screenshotAndName.testCapture.png")
      changeScreen()

      verifyAndRecordAndFail()

      val recordFileHash2 = getFileHash("$screenshotAndName.testCapture.png")
      assert(recordFileHash1 != recordFileHash2)

I think it is better to merge this fix, but we aren't able to reproduce the problem in our repository. Could you take a look?

[lukas-mercari]

@takahirom I believe the requirement to reproduce this is to make sure the task is taken from both configuration and build cache. (I can reproduce in the same way that I reproduced #374.)

Build cache: Because it means that the tests will be skipped.
Configuration cache: In this case the skip detection will not work properly because expectingTestNames is not initialised correctly.

@takahirom I upgraded to the latest version in our CI/CD pipeline, but it seems that sometimes we get the following exception:

...
Caused by: java.io.IOException: Source file wasn't copied completely, length of destination file differs.

My hypothesis is that it might happen that while one suite finished (and afterSuite is called), another is still generating images -- and thus files in the intermediate dir keep changing.

@lukas-mercari
Thanks. I saw a similar issue. Are you running a single variant?
#377 (comment)

[lukas-mercari]

@takahirom Yes, we only run a single variant per runner. (E.g. ./gradlew recordRoborazziDebug)

@lukas-mercari
If your hypothesis is correct, we might have to check if it is the root suite. Are you seeing multiple 'Roborazzi: test.doLast Copy files' logs?

In any case, we might need to include this if statement.

Could you please take a look at this PR?

Are you seeing multiple 'Roborazzi: test.doLast Copy files' logs?

Yes, I can see multiple logs (when running recording :sample-android:recordRoborazziDebug). Confirmed that the approach to find the root test suite seems to work!
