"gio open" handles mailto: links wrong, putting /// at the start of the email address

[Jonathan Kamens]

"gio open mailto:user@host" results in gio executing "thunderbird mailto:///user@host", which is wrong and causes the address that shows up in the thunderbird composition window to start with three slashes when it shouldn't.

Proof, from "strace gio open mailto:user@host" output:

16976 execve("/usr/bin/gio", ["gio", "open", "mailto:user@host"], [/* 76 vars */]) = 0
16980 execve("/usr/bin/thunderbird", ["thunderbird", "mailto:///user@host"], [/* 78 vars */] <unfinished ...>
