No need to add "/" at the end of url when url ends with "="
No need to add "/" at the end of url when url ends with "="

We should not add '/' to the end of url when url ends with '='. This was causing a malformed url to Parameter summary screen when viewing list of Parameters under Cloud Stack.
- Malformed URL: http://localhost:3000/orchestration_stack/parameters/10000000000005?show=/10r15
- Correct URL: http://localhost:3000/orchestration_stack/parameters/10000000000005?show=10r15
Issue was introduced in commit: 2e6ce4ccd76a724495dc016613418302afbb430c
