Exception in .gitignore plugin with git worktrees

[StefanHuebnerV]

Prerequisites

• Plugin is in the latest version
• Issue was not reported yet
• Stack trace (if provided) contains mobi.hsz.idea.gitignore package name

Description

The plugin doesn't handle git worktrees.
In a worktree, there is no ".git" subdirectory, but a ".git" file (that refers to the 'basic' checkout of the repository)
