No longer able to open KeePass files from within Nextcloud client

[monreal]

Steps to reproduce

1. Until a few weeks ago, so before 3.10 I think, I was able to open .kdbx files using KeePassDroid by selecting the file from the Nextcloud client
2. With recent versions like 3.10.1 the message "no app set up to handle this file type" is shown
3. Even "open with" does not let me select any app
4. However opening .kdbx files stil works from other apps like Solid file manager, so I guess it sis not a problem with KeePassDroid

Expected behaviour

• File should open in KeePassDroid

Actual behaviour

• see above

Android version: Lineage OS 16 (Android 9)

@monreal see #5009 (comment) this isn't an issue of Nextcloud but KeePassDroid (since it works perfectly fine with keepass2android)
