Frantisek Hrbata 00d77e7a75 fix(hints): properly identify source component
If there is a component(child) within a component(parent), like for test_apps, the parent
component may be wrongly identified as source component for the failed include. This may
lead to a false bug report if the parent component has component, which provides the missing
header, in requirements.

Fix this by looking for the longest matching source component directory.
