Not all Issues are listed in the taskbar (0.3.7)

Some issues are missing in the taskbar -- they are available and usable with `gtt` or gitlab itself.
The search function also doesn't show the issues.

Running on MacOs Mojave 10.14.4
Due to #37 I can't use version 3.10 so I'm using 3.7 of the gitlabb-time-tracker-taskbar
