* fix(lib/cli): relative paths, empty slides, and tests
This fixes two issues:
1. Empty slides are now reported as error, to prevent indexing error;
2. Changing the folder path will now produce an absolute path to slides, which was not the case before and would lead to a "file does not exist error".
A few tests were also added to cover those
* fix(lib): fix from_file, remove useless field, and more
* chore(tests): remove print
* [pre-commit.ci] auto fixes from pre-commit.com hooks
