Better status message when adding existing repo #1306
Description
Describe the bug
With Borg 1.2, Borg will pull a good amount of data before adding the repo. Currently we don't show a proper status message and just block the UI.
Proposed solution is to avoid blocking the UI and show a meaningful status message.
To Reproduce
Steps to reproduce the behavior:
- Add existing repo of +10GB or so size
- UI blocks for several seconds to a minute
Environment (please complete the following information):
- OS: macOS
- Vorta version: 0.8.4
- Installed from: macOS binary
