Crash while doing a seach inside a note: `NullPointerException: Attempt to invoke interface method 'void com.nextcloud.android.sso.api.NextcloudAPI$ApiConnectedListener.onConnected()'`

This issue respects the following points:

• I have read the FAQ
• I have searched for existing issues
• The issue affects the Notes Android app, neither the Notes server app nor the Nextcloud Android app.

Describe the bug

App crash while doing a seach inside a note.

Steps to reproduce:

1. open the app
2. click on a note
3. use the magnifying glass to search
4. type text
5. the crash occurs
   Seems to be occuring randomly and when the first few letters of a word that is in the note multiple times is typed. And for bigger notes it seems, like 60 lines and 10000 characters

Expected behavior

No crash when doing a search for text inside a note

Start by reproducing the crash through the note search steps and inspect the stacktrace entry at AidlNetworkRequest.java:69, where onServiceConnected is invoked. Trace which Notes Android search action reaches this SSO callback, then verify that repeated searches in larger notes no longer crash and that the reported stacktrace is absent.
