MethodRef Javadocs wrong for method with multiple arguments (space after comma doesn't work)

[robinst]

Steps to reproduce:

1. Add a LibraryModels implementation
2. Implement e.g. the castToNonNullMethods method and return a method ref with a signature like "<T>castToNonNull(T, java.lang.String)" (notice the space after the comma!)

Expected: It works, because the Javadocs example has a comma, see:

NullAway/nullaway/src/main/java/com/uber/nullaway/LibraryModels.java

Lines 189 to 190 in 6cec433

	* <li>signature is a method name plus argument types, e.g., <code>foo(java.lang.Object,
	* java.lang.String)</code>

Actual: The space doesn't make it work. Removing the space makes it work:

-"<T>castToNonNull(T, java.lang.String)"
+"<T>castToNonNull(T,java.lang.String)"

The Javadocs should probably be fixed, or spaces could be removed by methodRef.

Thanks for the report, I've put up #973 to fix the documentation.

Perfect, thank you!
