Assist for android shows HA not default assist app while it is.

**Description of problem, include YAML if issue is related to notifications:**
When updating from a version without "Assist for Android" while HA is set as the default assist app, when opening the "Assist for Android" screen for the first time it shows as not default, while it is, requiring to change it to a different app/none first and then back. This is not a major problem but I did encounter it and maybe other people will too.
