When add snapshot name manually, it isn't extracting the class name

[tonilopezmr]

Expected behaviour

When enabling testClassAsDirectory = true and you add a snapshot name manually like snap.matchWithSnapshot(anyObject, "snapshot name"), It should add a folder with the class name and add a file with the name snapshot name.snap

Actual behaviour

testClassAsDirectory = true but when you add a custom snapshot name, it isn't creating any folder with the test class name.

Steps to reproduce

val snap = KotlinSnapshot(testClassAsDirectory = true)
snap.matchWithSnapshot(anyObject, "snapshot name")
