Previously, when the test compiler had been seeded with a resource
file, any modifications to this resource performed during
compilation would be lost as this original content would always
be returned.
This commit updates the DynamicJavaFileManager to always store
the dynamic resource in the dynamicResourceFiles map, irrespective
of whether it's being created afresh or from some existing resource
content. This ensures that any modifications made to the resource
can be retrieved later on.
Similarly, DynamicClassLoader has been updated to prefer dynamic
resource files over any original resource files. This ensures that
the resource that it finds reflects any modifications that have
been made to it.
