Thomas Huth 0f0a9e4e5c tests/qtest/migration-test: Fix unlink error and memory leaks 
When running the migration test compiled with Clang from Fedora 37
and sanitizers enabled, there is an error complaining about unlink():

 ../tests/qtest/migration-test.c:1072:12: runtime error: null pointer
  passed as argument 1, which is declared to never be null
 /usr/include/unistd.h:858:48: note: nonnull attribute specified here
 SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior
  ../tests/qtest/migration-test.c:1072:12 in
 (test program exited with status code 1)
 TAP parsing error: Too few tests run (expected 33, got 20)

The data->clientcert and data->clientkey pointers can indeed be unset
in some tests, so we have to check them before calling unlink() with
those.

While we're at it, I also noticed that the code is only freeing
some but not all of the allocated strings in this function, and
indeed, valgrind is also complaining about memory leaks here.
So let's call g_free() on all allocated strings to avoid leaking
memory here.
