[java] Fix NPE in CloseResourceRule

[jsotuyod]

Rule: CloseResource

Describe the PR

When using type inference and initializing through a method call rather than a direct constructor call, the rule would detect the var as being a Closeable, yet fail to retrieve the proper type to check if it was whitelisted / which error message to produce.

We now look at wether there is type inference in play when deciding wether computing the runtime type is required.
