Incorrect import of classes in files that are part of a library in 5.0.0-nullsafety.1

[denniskaselow]

This works in 5.0.0-nullsafety.0 but doesn't work in 5.0.0-nullsafety.1:

// foobar.dart
library foobar;

part 'src/part.dart';

class Foo {
  void doSomething(Part part) {}
}

// src.part.dart
part of foobar;

class Part {}

// foobar_test.dart
import 'package:foobar/foobar.dart';
import 'package:mockito/annotations.dart';
import 'package:test/test.dart';

import 'foobar_test.mocks.dart';

@GenerateMocks([Part])
void main() {
  test('do something', () {
    final foo = Foo();
    final part = MockPart();

    foo.doSomething(part);
  });
}

5.0.0-nullsafety.0 correctly imports foobar in foobar_test.mocks.dart:

import 'package:mockito/mockito.dart' as _i1;
import 'package:foobar/foobar.dart' as _i2;

5.0.0-nullsafety.1 incorrectly imports the part file instead of the library in foobar_test.mocks.dart:

import 'package:mockito/mockito.dart' as _i1;
import 'package:foobar/src/part.dart' as _i2;

Happy new year by the way ;).

Ouch. *cringe* sorry about that. Good catch.
