fix(test): file.spec.131 moveTo may fail due to read order assumption

[breautek]

Platforms affected

tests

Motivation and Context

On iOS (and I think any file api I've ever used), reading directories does not define any particular order of files. The iOS implementation uses contentsOfDirectoryAtPath:error: which states:

The order of the files in the returned array is undefined.

While this test does not appear to be failing actively on GH actions, it was failing for me locally due to the expectation assuming that they will be in a particular order.

Description

Reworked the test so that it will scan for each expected value and keep track which ones it has found.
Assertions of the expected item count remains.
Asserts that each item is found.

Testing

Ran mobilespec locally on iOS.
