Watching android class ignores dump-args, etc.

[aph3rson]

Describe the bug When using the android hooking watch class ... function, the CLI suggests the --dump-args, --dump-backtrace, and --dump-return arguments. However, these don't appear to be respected.

To Reproduce Steps to reproduce the behavior:

1. Launch objection pointed at an Android application
2. Pick a random class with callable/called functions
3. Run android hooking watch class clazzhere --dump-args --dump-backtrace --dump-return, as suggested

Expected behavior Similar functionality to the android hooking watch class_method clazzhere.method() --dump-args --dump-backtrace --dump-return function.

Environment (please complete the following information):

• Device: Moto G6
• OS: Android 8.0.0
• Frida Version 12.4.0 (server)
• Objection Version: 1.5.2

Additional context If it matters at all, the app I'm testing is a Xamarin app - hence the weird class path.
