Remove an unused type parameter from the 'nocache' function (#135)

* Remove an unused type parameter from the 'nocache' function

The function is currently unusable because the type parameter has no
uses or bounds.

* Fix existing rustfmt violation

Semicolons need to be added to return statements.

Without this, the build fails.

* Replace call of Uri::port to Uri::port_part

The former is deprecated in favor of the latter.

This causes a deprecation warning when compiling shiplift.

This patch fixes the deprecation warning.
