Suppress unchecked warning in GeoApiContextTest

[apjanke]

What do you think about suppressing this unchecked-conversion warning in the GeoApiContextTest? Since it's just in a test using mock objects, I think that'd be acceptable.

When compiling now, I get this "note" output from the test compilation step.

> Task :compileTestJava
warning: [options] bootstrap class path not set in conjunction with -source 1.7
Note: /Users/janke/local/repos/google-maps-services-java/src/test/java/com/google/maps/GeoApiContextTest.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

With -Xlint:unchecked on:

> Task :compileTestJava
warning: [options] bootstrap class path not set in conjunction with -source 1.7
/Users/janke/local/repos/google-maps-services-java/src/test/java/com/google/maps/GeoApiContextTest.java:82: warning: [unchecked] unchecked method invocation: method get in class GeoApiContext is applied to given types
    builder.build().get(new ApiConfig(path), fakeResponse.getClass(), params).awaitIgnoreError();
                       ^
  required: ApiConfig,Class<? extends R>,Map<String,String>
  found: ApiConfig,Class<CAP#1>,Map<String,String>
  where R,T are type-variables:
    R extends ApiResponse<T> declared in method <T,R>get(ApiConfig,Class<? extends R>,Map<String,String>)
    T extends Object declared in method <T,R>get(ApiConfig,Class<? extends R>,Map<String,String>)
  where CAP#1 is a fresh type-variable:
    CAP#1 extends ApiResponse from capture of ? extends ApiResponse
2 warnings

I've taken a stab at it, and I can't figure out how to wrangle the types to get it to compile without the warning, while using the dynamic getClass() off the mocked ApiResponse object.

This codebase is pretty close to a warning-clean build; this gets one step closer.

Sounds reasonable to me.
