Describe the bug
remove Prefix done't seems to work correctly in proxy mode

To Reproduce

• create a new env without any / only teh default route
• set prefix to e.g. "business/services/cvpn"
• enable proxy with something like "https://[target]/some/test/url"
• enable "remove prefix"

Wenn make a call e.g. https://[mockoon]/business/services/cvpn/groups the requested call is

https://[target]/some/test/url/business/services/cvpn/groups

and no prefix is removed.

Expected behavior
I expect prefix to be removed from incoming call. In this case:

https://[target]/some/test/url/groups
