PyPI API requests should properly redirect when accessed through the router

Steps to reproduce:

• Configure a local PyPI repository "pypi-local".

• Configure a baseurl in the global settings

• Open $BASEURL/artifactory/api/pypi/pypi-local/simple (note the missing trailing slash)

Expected result:

• Redirect to $BASEURL/artifactory/api/pypi/pypi-local/simple/ (note the trailing slash)

Actual result:

• Redirect to http://localhost:8081/artifactory/api/pypi/pypi-local/simple/

Notes:

• This correctly works for non-api requests:

  $BASEURL/artifactory/pypi-local -> $BASEURL/artifactory/pypi-local/

• When explictly providing the header  X-JFrog-Override-Base-Url it is used.
