Fix EZP-21722: Error with the ez_render_field if a custom tag xsl stylesheet is not properly loaded

If a nonexistent file is listed in the ezpublish.yml, ez_render_field()
will silently fail its render. This little check throws an exception if
an XSL stylesheet is missing.

Closes #557
EZP-21723: Optimize search count for pagerfanta adapter a bit.

See @andrerom's comment on #558:

> This could be optimized as the totalCount will be generated by the

Note that it's just a tiny optimization since we cannot predict in which
order getNbResults() and getSlice() are called. This optim assumes that
getSlice() is called first.
