teams: fix absolute path usages

There are some references to absolute paths in the Teams application
code:

  * /usr/share/pixmaps - The application icon.
  * /usr/bin/xdg-mime - Uses absolute path to invoke.
  * /usr/bin/teams - Uses absolute path in the autostart file if
                     configured to start automatically at login.

Though the paths are hardcoded they can be easily changed within
the application’s main JavaScript code bundle and so we’ll do just
that.

This should at least fix auto-start not working, even when enabled.
