[BUGFIX] Install Tool: Avoid caching

Install Tool bootstrap initializes the cache system and sets
all caches to NullBackend for increased stability of the tool.
Install Tool submodules however, that later call a bootstrap method
to additionally load ext_tables and friends for some scenarios,
indirectly call a method to set caches to the default values
without NullBackend again. As result, Fluid views are sometimes
cached again.
The patch supresses this by opening further detail methods of
the Bootstrap and calls them directly without pushing a
cache configuration again.
