Summary
Closes #1526
The logic for seeing if a port was already in use came after the user-provided port (or the default, 8080) was assigned to the devServer and plugins. This meant that plugins like Prefresh were given say port 8080 to run on, but the server actually ended up listening on 45454 because 8080 was taken.
Does this PR introduce a breaking change?
