Update OTR Profile API in Window AppleScript.

Profile API is being updated (issue 1033903) and the usage of
GetOffTheRecordProfile and HasOffTheRecordProfile without argument is
getting deprecated. Use cases of this call that ONLY refer to incognito
or guest mode can use [Get/Has]PrimaryOTRProfile() instead.

This CL does not change any behavior and is just code clean up.
