TST: Fix image comparison directory for test_striped_lines

QuLogic · QuLogic · commit 5bd9a6084560 · 2024-08-20T18:52:32.000-04:00
The image comparison directory is determined by `inspect.getfile(func)`,
but when a test is wrapped in `rc_context`, the file returned is
`contextlib` since that decorator is `contextlib.contextmanager`. Since
this test uses `check_figures_equal`, that doesn't break it, but it does
break the `triage_tests.py` tool as it cannot find a corresponding
baseline image directory.

Moving the `rc_context` decorator above `check_figures_equal` fixes the
determined directory. While in this case, the context doesn't set
anything that would affect figures, it also makes sense to set the
context before figures are created.
