modules pytest migration flag fails to remove symlinked pytest directories

[jfy133]

Description of the bug

Some tools that have a subcommand named build did not work with the pytest implementation of module tests.

The workaround was to make a symlink of the module name from build to something called build_test

(example: MALT/BUILD).

During nf-core modules create malt/build --migrate-pytest) I got an error message saying that it could not remove symlinks, so the migration failed.

This then meant pytest files were still under the test/ directory, and was not removed from the pytest tags yml file.

(Unfortuantely I don't have it on my terminal anymore due to other traceback)
