Consider skipping meaningless components when calculating path distance

[marco-c]

E.g. test, src, tests.

Can you point me to the files that calculate the number of common components? I'd like to take up this issue but I want to understand it first.

[marco-c]

@BBloggsbott there are a few dependencies for this issue, so it can't be worked on yet.

[BBloggsbott]

@marco-c Oh. Okay. What are the dependencies?

[marco-c]

There are quite a few, this part of the project is very much a work in progress.

[BBloggsbott]

Ah. Okay. Is there any way I can contribute to it?

[marco-c]

To this part of the project, not yet. To bugbug in general, sure! Yon can pick up any good first issue (https://github.com/mozilla/bugbug/issues?q=is%3Aissue+is%3Aopen+label%3Agood-first-bug), but please follow #1092 first.

I've tried it and it didn't seem to make almost any difference. I want to keep this open though and try again after we increase the training set again.
