Subject: tty: truecolor check moved before 256 check

256 color would be return instead of 16m if both env variables were set

* tty: improve color check order highest spec first
* tty: add test for TERM and COLORTERM set
* tty: move COLORTERM check outside TERM closure
* tty: remove extra if check for COLORTERM
