Fixed four test issues within test code. (#7662)

### Description

This PR fixed the three issues within the test code that could cause
problems during CICD.

Three issues:

tests/test_pad_collation.py line 120: supposed to be assertEqual, but
not assertTure? or it will always be true.
tests/test_to_numpy.py line 74: Same as above.
tests/test_auto3dseg.py line 370: typo? two same asserts next to each
other.
tests/test_compose.py line 719, 725, 727: Should be assertEqual instead
of assertTrue
