Ensure we clean log files before testing with Nuke

[andrewlock]

Summary of changes

Cleans the log file directory before running tests

Reason for change

Some tests assert on the presence/absence of log files. Tests should handle cleaning up before they run, but this is a stop gap.

Implementation details

Clean the test logs directory before running the tests

Test coverage

This is the test

Execution-Time Benchmarks Report :stopwatch:

Execution-time results for samples comparing the following branches/commits:

• This PR (5950)
• master

Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:

• Welch test with statistical test for significance of 5%
• Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

Benchmarks Report for tracer :snail:

Benchmarks for #5950 compared to master:

• 1 benchmarks are faster, with geometric mean 1.257
• 1 benchmarks are slower, with geometric mean 1.297
• 1 benchmarks have more allocations

The following thresholds were used for comparing the benchmark speeds:

• Mann–Whitney U test with statistical test for significance of 5%
• Only results indicating a difference greater than 10% and 0.3 ns are considered.

Allocation changes below 0.5% are ignored.
