fix: reviewing TODOes at v19 (#5303)

## Issue being fixed or feature implemented
During reviewing TODO were found some TODOes that can be done now.

## What was done?
 - fix: follow-up dash#3467 - replaced commented code to disabled code
- follow-up bitcoin#16394 - uncommented code related to `watchonly`
feature
 - removed out-dated TODO in `rpc/masternode.cpp` (already done)
- fix: renamed name of clean up test_unittests: removed TODO and updated
name of variable TRAVIS
 - rewritten todo inside `.travis.yml`
 - fix: adds a missing description for result of rpc `mnsync`

Last commit (`mnsync`) is an only candidate for backport to v19, other
changes are non significant.

## How Has This Been Tested?
Run functional/unit tests
