Unify branch name with pytest id for integration tests

[slimreaper35]

Some branches in https://github.com/cachito-testing/integration-tests/branches use different names for test cases than what we have as an id for pytest. Let's be consistent and use one name (it can be a completely new name) for the branch name as well as pytest id

This will lead to renaming some test data directories that need to correspond to particular pytest id.

Example:

            utils.TestParameters(
                branch="bundler/missing-git-revision",
                packages=({"path": ".", "type": "bundler"},),
                check_output=False,
                check_deps_checksums=False,
                check_vendor_checksums=False,
                expected_exit_code=1,
                expected_output="Failed to parse",
            ),
-            id="bundler_malformed_lockfile",
+            id="bundler_missing_git_revision",
