fix: edge case - disable autosave delay after triggering a save

User might trigger the autosave delay timer and disable autosave delay or autosave.
This commmit fixes potential issues from the timer triggering after the feature is disabled.
The timer now checks if the feature is still enabled when triggered.
Adds tests for those edge cases as well
