EXT:backend generates a URL to EXT:install, but has no dependency. This
can lead to composer setups with EXT:backend but without EXT:install,
leading to an exception while generating route.

Therefore a suggest is added as a hint to install also EXT:install.
Existing code is wrapped with an try / catch in order to work under both
circumstances.
