Fix rendering of entry title in Twig views

Fix rendering of entry title in Twig views

This commit provides some improvements on the rendering of entry title
on entries list and entry views and refactors filter calls:
- Remove escape filter from apparent title, striptags is enough
- Move raw filter to the end of apparent title as it's ignored if not
  placed as the last filter
- Replace raw filter with e('html_attr') for title used in attributes,
  fixing possible issue and/or glitch
- Add striptags to entry.title used for link sharing to respect the
  apparent title

Fixes #2802
