test: fix cross-platform path comparison in merge and ideation tests

- test_init_converts_path_to_pathlib: Remove string comparison
  since Path separators differ by platform (/ vs \\)

- test_init_default_parameters: Use project_dir.resolve() when
  constructing expected storage_dir since the implementation
  resolves the project_dir before computing storage_dir
