Replace endsWith() with isDefaultLib()

Browse Source 
There are a couple of issues with using the current endsWith() function to determine if we should allow a rename for default lib files:
1. XXXX-lib.d.ts would not allow renames even though it should as the preceding characters are not being verified for directory separators
2. There is the potential for false matches as there is currently no check to verify indexOf was successful (index >= 0)
