Since MethodCall equality checks are limited to test scenarios, this patch replaces them with an equivalent test matcher. At present MethodCalls are always used in scenarios where indentity-based equality/hashing is appropriate. This change avoids an assertion failure when MethodCall args are Iterable (possible since args are of type dyanmic), and hashValue() from dart:ui asserts that its input is not an Iterable. The alternative of implementing support for deep equality in dart:ui was rejected on the basis that if we're to encourage performant code, expensive checks should be obviously-expensive to the author.
