Import fakeDynamicImport from enzyme-adapter-utils

Change the import from `enzyme-test-utils/src/Utils` to
`enzyme-test-utils`.

The test results are same in both way. But the coverage is broken
when we import from `enzyme-test-utils/src/Utils`. I'm not sure
why but maybe this breaks the tested lines / branch computation
in nyc.
