WARNING: cannot create user data directory: failed to verify SELinux context of /home/idea/snap: exec: "matchpathcon": executable file not found in $PATH

Whenever I start taskbook I got this warning:
2019/04/16 20:27:19.690644 cmd_run.go:876: WARNING: cannot create user data directory: failed to verify SELinux context of /home/idea/snap: exec: "matchpathcon": executable file not found in $PATH

**Expected behavior**
no warnings
**Screenshots**
If applicable, add screenshots to help explain your problem.

**Technical Info (please complete the following information)**
- OS: UBUNTU 18.10
- kernel 5.07
- Node.js Version: 8.11.4
- Taskbook Version: 0.3

Start by reproducing the warning when launching taskbook on Ubuntu 18.10 with the listed Node.js and Taskbook versions, then trace the startup path that reports the missing matchpathcon executable. Done means taskbook starts without this warning, including on systems where matchpathcon is not available.
