only swith to shell tty mode if interactive

Browse source 
My PR #2578 had the unexpected side-effect of altering the tty modes of
commands run via "fish -c command" or "fish scriptname". This change fixes
that; albeit incompletely. The correct solution is to unconditionally set
shell tty modes if stdin is attached to a tty and restore the appropriate
modes whenever an external command is run -- regardless of the path used to
run the external command. The proper fix should be done as part of addressing
issues #2315 and #1041.

Resolves issue #2619
