Makes tests conditional on having Catalyst::Runtime 5.90030 installed

To ease the depreciation process Catalyst::Runtime is including
Catalyst::DispatchType::Regex as a requirement for a period of time.
This causes a circular dependency. The installers seem to be smart
enough to deal with the circular dependency, but the CDR tests fail
because Catalyst::Runtime 5.90030 isn't installed. The test will be
re-enabled once the requirement has been removed from Catalyst::Runtime.
