jest extended snapshot matchers don't work with snapshot name

[sparten11740]

Jest allows passing a snapshot name to snapshot matchers such as toMatchSnapshot and co, e.g.

expect(obj).toMatchSnapshot('inital state')
expect(obj).toMatchSnapshot('state after reload')

The full test name in that case is suffixed with : ${hint}.

exodus-test always assumes the passed argument to be a property matcher and disregards the overloaded signature

test/src/jest.snapshot.js

Lines 113 to 120 in eec3fa5

	const snapOnDisk = (expect, orig, matcher) => {
	if (matcher) {
	expect(orig).toMatchObject(matcher)
	// If we passed, make appear that the above call never happened
	const state = expect.getState()
	state.assertionCalls--
	state.numPassingAsserts--
	}

So before even attempting to extract the snapshot from the snapshot file, exodus-test throws in this line because it passes a string to toMatchObject

for reference, these are the supported signatures in jest

{
  toMatchSnapshot<U extends { [P in keyof T]: any }>(propertyMatchers: Partial<U>, snapshotName?: string): R;
  toMatchSnapshot(snapshotName?: string): R;
}
