Clear app details cache before checking in paths

The app data, when set by `rebar3_app_discover` basically does not
include the modules if it was derived from the .app.src file, even if at
a later point the modules were compiled.

Since there is currently no clear way to add that information reliably
across all compiler versions in all types of compilers, we simply clear
the cache and re-derive the information when required.

This might have a small performance cost, but is required for
correctness whenever an application's first build is run. Specifically,
this bug was detected when a plugin included lager's parse transform,
and the application itself also required it, but two distinct versions
were needed.

This patch finalizes fixing this issue.
