Fix `getImplmentation` Methods

[taljacob2]

In Object.c
Fix getImplementation Methods:

Do not EVER use concat and then free the returned conatted string.
This will cause the memberName to be freed from memory, and then you would not be able to search for the member within the Object.

Instead of using concat, you should use a const string as a memberName.
For example:

• a "literal" const char * string
• a #define macro that its value is a const string.
