flutter test sets current directory differently depending on how test was executed #20907
Description
Moving from Dart-Code/Dart-Code#1156 as this seems to happen from the command line. Depending on whether you pass a filename to flutter test or just run all tests (or filter using --plain-name or whatever) the value of Directory.current will be different.
Since flutter forces you to run flutter test from the root (eg. you can't influence the working directory yourself) these should probably be consistent.
