Removes terminal cursor caret if not run in git repo

[clemisch]

I installed the Linux binary via

$ curl -sf https://gobinaries.com/augmentable-dev/tickgit/cmd/tickgit | sh

When I run tickgit in a directory which is not a git repo, I correctly get the error

/home/clemisch/.git is not a git repository

After that, I don't see a cursor caret in my terminal. I have to run reset or open a new terminal.

I'm on Ubuntu 18.04. Terminal is guake, gnome-terminal or xterm.
