App crashed after removing table

[pawlosck]

Describe the bug App crashed when I removed table created some time ago via web app. There is only one table.

Steps to reproduce the behavior:

1. Create table via web app
2. Install Android app via fdroid
3. Login to app using existed account in Android
4. Open Android app - App will display created table. Screen will be switched beetwen table name and someting other. Table name will be changed for a moment (about 1/10 second) and next display correct table name. After 1-2 seconds, table name changed again.
5. Remove table from Android App. App crashed

Expected behavior Table should be removed and app should display list of existed tables
