From time to time, the bundle generation duration may be unexpectedly
increased by assets modifications.
In order to avoid that, this commit adds two tests that generates all
the bundles. One of the test is only meant to log the duration in order
to monitor it. The other test is ensuring that a bundle generation does
not take more than 2 seconds.
Pay attention that the purpose is not to test the generation of the
bundle, any error during generation is logged as an information.
Also, warnings are silently ignored.
