Initial set up fails

[gadgetguy08]

Description of the issue

Behaves similarly to issue #95.
When attempting to access News Reader on Nextcloud, OCReader returns me back to the prompt to enter a server address. OCReader does not proceed further than giving access to the Nextcloud-account; tapping on grant access leads to the initial prompt for server name.

The Nextcloud app can get access through the same login procedure as OCReader's.

Expected behavior

Should allow access to News Reader app.

Steps to reproduce

1. Start app
2. Enter Server Address, press "Continue"
3. On Connect to your account, press "Log In"
4. Enter Username (email) and password and press "Log In"
5. On Account Access screen, press "Grant Access"
6. Nextcloud registers it
7. Returns to first screen (Step 2).

Your Environment

• OCReader version: Anything greater than 0.44
• Nextcloud news version: 14.2.2
• Android version: 9.0

---

Nextcloud server log shows
"Warning core Login failed: 'name%40email.com' "

When I put the user name (email address) in single quotes, I get this from the NC server log:
"Warning no app ... Login failed: 'name@email.com' "
