    bitbake: cooker: ensure we can run buildFileInternal() after cache is populated
    
    If you run some other operations that result in the cache being
    populated, and then call buildFileInternal(), then you can end up in a
    situation where the cache already contains information about the recipe.
    For example in OE this can now happen when you use devtool upgrade.
    Normally this doesn't cause any problems, unless you have a non-absolute
    path in BBLAYERS - in buildFileInternal() we are calling matchfile() which
    will convert the filename to absolute, but later when taskdata goes to find
    the providers of the recipe it finds the non-absolute path, sets up the
    task information using this and then the runqueue can't find any tasks
    matching the absolute path. To fix this, back out the optimisation I did
    earlier in bitbake rev ba53e067a2d448dd63b4ca252557ce98aa8e6321 to avoid
    calling parseConfiguration() again, which is unfortunate but does result
    in the cached information being that causes the problem being cleared
    out.
    
    This fixes "Task do_unpack does not exist for target ..." running
    devtool upgrade within intel-iot-refkit.
