TASK add info to exception: 1355480641 - use of ./flow flow:package:rescan might fix your problem

When working on several branches with changing dependencies. Sometimes you are hit with the exception 1355480641. This means, that a composer.json file is missing in a package.

When it appears after switching branches and composer install, the execution of ./flow flow:package:rescan should help in most of the cases.

As a developer I want to display usefull hints on how to fix a problem, in order to work efficient.

To achieve that, I suggest to add the following hint to the exception text:

• When this error occurs after switching branches and/or a composer install, you might want to run ./flow flow:package:rescan and ./flow flow:cache:flushand optional ./flow flow:cache:warmup to get the internal state corrected
