Testing behavior when `obsidian-include-hidden-files` is set to `t`. These tests should pass after #93 is merged into master.

Update cache after `obsidian-move-file` by removing old file path and inserting new file path. Also adds a new test to test this functionality.

Removes dependency on projectile by using the functionality of the built-in `project.el`. Closes issue #24
