Crash when trying to edit SFTP connection (port = empty string)

[Firepal]

Describe the bug App crashes Guru-Meditation-style when editing an SFTP connection (with an IPv6 adress). (I don't use IPv4 for SFTP connections and haven't tried it yet)

To Reproduce Add an SFTP cloud connection with an IPv6 address, then once created, try to edit it.

Expected behavior Well.... it shouldn't crash when you try to edit the connection.

Whoops; unrelated to IPv6. And duplicate of #3300

Nevermind, the crash log is different. Separate issue!

This thing is acting up because of the port variable, it seems. I didn't change it, it was 22 by default and that seemed to have worked fine.
