time_travel still time travels during an exception

[antazoey]

What happened?

I tried time traveling to the same time as the current timestamp, and it errored. However, the pending timestamp still seems to have changed.

Code that produced the error

In [2]: type(evm_backend)
Out[2]: eth_tester.backends.pyevm.main.PyEVMBackend

In [3]: current_ts = evm_backend.get_block_by_number("pending")["timestamp"]

In [4]: current_ts
Out[4]: 1722534117

In [5]: evm_backend.time_travel(current_ts)
ValidationError: timestamp must be strictly later than parent, but is 0 seconds before.
- child  : 1722534116
- parent : 1722534116.

In [6]: evm_backend.get_block_by_number("pending")["timestamp"]
Out[6]: 1722534116

Full error output

File ~/virtualenvs/ape08/lib/python3.12/site-packages/eth/vm/base.py:712, in VM.validate_header(cls, header, parent_header)
    710 # timestamp

    714         f"but is {parent_header.timestamp - header.timestamp} seconds before.\n"  # noqa: E501

    717     )

ValidationError: timestamp must be strictly later than parent, but is 0 seconds before.

Fill this section in if you know how this could or should be fixed

I am not sure! Somehow revert any changes or validate sooner?

btw, non-urgent, as I don't get use this issue when I use EthereumTester class directly rather than evm backend
