Describe the bug
Access error due to other user owning the same /tmp/mkdp-nvim.log file.
This happens whenever 2 users on the same machine want to use the plugin.

To Reproduce
Steps to reproduce the behavior:

1. Run plugin with one user on the machine. Alternatively just such chown root /tmp/mkdp-nvim.log to emulate such behavior.
2. Try running plugin as yourself.
3. See error.

Expected behavior
Error-free behaviour even if other user on the same machine uses plugin
