api/router: avoid unneeded loops and fix path match (#1594)

* api/router: avoid unneeded loops and fix path match

* if match found in google api path syntax, not try pcre loop
* if path is not ending via $ sign, append it to pcre to avoid matching other strings like
  /api/account/register can be matched to /api/account
* api: add tests and validations
