Fix button breakage on viewContribution

[eileenmcnaughton]

Overview

Several buttons on the View Contribution form are not working due to a malformed url

Before

e.g Record Payment is broken

After

Fixed - also these work

Technical Details

The url was being run through CRM:url in the php layer which was not 'desired' for the bottom buttons in the tpl layer - this removes that & sets the other place that calls them to expect to call crm.url

Comments

We will backport to 5.48
