Added missing translations, and fixed a few issues in other translation files.

The diagnostic is made of various data about the node:
- id and legacy id
- commit, version, including OS
- state of channels
- state of the swap-in wallet
- state of the final wallet
- state of connection/electrum

Logs may not contain all the needed data (as they are trimmed regularly) and
also are more difficult to parse.

On Android the correct code is "in" for Indonesian, not "id".

Fixed a few warning in the gradle file, and moved android test
to unit test folder.

This is the iOS pendant of the already existing Android screen.

This allows iOS users to recover funds that have been sent to their
channel's address by mistake.
