We never did (and still do not) guarantee any order in which terminal emulators
are tried. Quoting from the i3-sensible-terminal man page:
> Please don’t complain about the order: If the user has any preference, they
> will have $TERMINAL set or modified their i3 configuration file.
This commit moves mate-terminal to the beginning of the list, which is
considered the most accessible terminal emulator among blind users.
