delete_exe option not working properly

[BenWibking]

Running in production, the --delete_exe option does not work as expected:

   Sedov-GPU PASSED
   removing subdirectories from test directory...
   removing compressed plotfiles from test directory...
   removing executable from test directory...
Traceback (most recent call last):
  File "/tmp/bwibking/_work/2/s/./extern/regression_testing/regtest.py", line 1354, in <module>
    n = test_suite(sys.argv[1:])
  File "/tmp/bwibking/_work/2/s/./extern/regression_testing/regtest.py", line 1251, in test_suite
    os.remove(executable)
FileNotFoundError: [Errno 2] No such file or directory: 'Sedov-GPU.ex'

Somehow I caused this problem, but it's not immediately obvious how to fix it...

Directory structure:

bwibking@avatargpu:~/regression-tests/quokka-tests/2025-02-12/Sedov-GPU> ls
blast_unigrid_128_regression.in  Sedov-GPU.make.out                    Sedov-GPU_plt10978.gasDensity.YZ.ppm
Sedov-GPU.compare.out            Sedov-GPU_plt10978.gasDensity.XY.png  Sedov-GPU.run.out
Sedov-GPU.err.out                Sedov-GPU_plt10978.gasDensity.XY.ppm
Sedov-GPU.ex                     Sedov-GPU_plt10978.gasDensity.XZ.ppm

Also, the pass to remove the executable from the test directory only runs after the last test is run, rather than after each test, which is odd.
