[BUG] Android/tv-casting-app: NPEs

[sharadb-amazon]

Reproduction steps

1. Make temporary changes to the Linux tv-app, so it does not advertise any device name in the DN TXT Record (can be done in Advertiser_ImplMinimalMdns.cpp)
2. Discover the tv-app using the Android tv-casting-app.
3. Observe NullPointerException in Stacktrace 1 below.

Also, stacktrace 2 and 3 have been observed in other testing.

Generally, the Android tv-casting-app needs some defensive checks to avoid these crashes.
