White space causes backup/restore to fail

[atymic]

1. Database version (Ex: PostgreSQL 10.0): Any

2. TablePlus version (the number on the welcome or about screen, Ex: build 81): 355

3. Linux distro (Ex: Ubuntu 18.04): 20.04

4. The steps to reproduce this issue:

• Copy server IP into ssh box, with some kind of whitespace at the end (newline or space)
• Open connection, works fine (guess the whitespace is silently trimmed somewhere in the main app)
• Try to backup/restore and get a non obvious error

It seems that the white space breaks backup/restore. Ideally when saving the connection white space should be trimmed, or at least a better error should be shown to save ages of debugging :)
