SpringBasedCoherenceSession does not honor coherence.cacheconfig property

[lyiu18]

When coherence.cacheconfig is set, the config file this property point to will be treat as default

However, in the current code

if I use default constructor, it will not load current property file (only load coherence default)
if I use correct URI in constructor, it will not associate as default ConfigurableCacheFactory

either way won't way.

need code change to check that situation.
