snapFilenameExtension cause removing of snapshot after test

[dorley]

When defining snapFilenameExtension (e.g. to empty string), the snapshot image will be removed after execute method call to 'matchImageSnapshot', if removed 'snapFilenameExtension' then it will work just fine.

Sample code:

addMatchImageSnapshotCommand({
failureThreshold: 0.2,
capture: 'viewport',
// snapFilenameExtension: '',
})

I use it in the same way, and problem occurs too for me

There is a specific test case to allow snapFilenameExtension to be an empty string, so this should be fine. For that reason I need a more robust reproduction of the issue to make that test fail

Can you also check #48 and see if that is related?
