Bump minimum version of Dancer2 to 0.140001
Directly set the port in Dancer2::Runner in lifecycle tests.

Another alternative would be to rewrite the tests to use Plack::Test.
(Need to find a toit for that..)
Merge branch 'pr/update_for_d2_140001'
Remove context usage:

Without the context object, you need to call the App to destroy the
current session.
