NIFI-12785 Refactored InvokeHttp code to avoid double encoding of the entered URL.

[dan-s1]

This PR aims to solve the problem of the issue reported regarding URLs being double encoded. The refactor for this PR entailed keeping the fix for NIFI-12513 intact for validation but for actual use, the url is used in InvokeHttp as it was entered by the user. #8459 is the backport of this fix to v1.
