[BUGFIX] Retry Uri Building after exception

[saitho]

What this pr does

When there are route enhancers defined for a page containing the Solr search plugin, e.g. to realize pretty URLs for the search term, filters or pagination, there are issues with the URI caching that utilizes placeholders. Placeholders usually do not get replaced, leading to the issue described in #2984.

This PR implements a solution for route enhancers that define requirements in their parameters. The requirements are checked against the placeholders, leading to an exception. This exception is caught and it will then proceed the URI building with the original arguments instead of the placeholder arguments.

Fixes: #2984

How to test

Scenario 1: Speaking URL for search term

See #2984

Scenario 2: Speaking URLs for pagination

1. Set up the following route enhancer (set the page containing the Solr list plugin in limitToPages):

routeEnhancers:
  SolrPagination:
    type: Plugin
    namespace: 'tx_solr'
    routePath: '/{page}'
    defaults:
      page: 0
    requirements:
      page: '\d+'
    limitToPages: [1]

2. Clear TYPO3 cache
3. Open the Solr list plugin (e.g. https://mysite.dev/search)
4. The pagination links should be pretty (e.g. https://mysite.dev/search/1, https://mysite.dev/search/2)
