fix(react-docgen): add ObjectMethod support to resolveName

Extend the resolveName function in getMemberExpressionValuePath.ts to
handle ObjectMethod nodes, preventing the error below from being thrown
during AST resolution of member expressions within object methods.

TypeError: Attempted to resolveName for an unsupported path. resolveName does not accept ObjectMethod.

Fix #902
