feat: improve search as a primary means to create new pages

Specifically, this pull request checks if the current query is already a
valid pageid and then return that as suggested pageid.

Also, tests are added for this method.

some basic framework to do at least some HTML validity checking

Checks are done against the w3.org validator API. Currently we have some
fails. One will be fixed in #2314, others still need to be fixed.

This integration test also reveals some code bugs because texts do not

make testing of inaccessible methods easier

While it's generally frowned upon testing privates, it can often be
useful and the easier way to write tests. Eg you want to test something
complicated method that is important, but you do not want to expose it
directly to other classes...

This new method uses reflection to make access to such methods possible
from within tests without the need for intermediate classes.

feat: add a simple unparser for parsed search queries

To allow creating links with manipulated versions of the current search
query an unparser is necessary. However, the current output of ft_queryParser
makes some advanced features hard to detect. Therefore the new
ft_queryUnparser_simple cannot handle negated phrases and `OR` searches.

It should still cover 98% of search queries.
