Unused snapshots when running on filename (test_a.py) that's the prefix of another (test_abc.py)
**Describe the bug**

I have a project that has filenames where the non-`.py` part happens to be a prefix of another (e.g. `test_a.py` vs. `test_abc.py`). When running `test_a.py` in isolation, syrupy picks up the snapshots from `test_abc.py` and either warns/errors about them or deletes them (depending on if `--snapshot-update`) is specified.

(Thanks for syrupy!)

**To reproduce**

```python
# test_a.py
def test_foo(snapshot): assert snapshot == "a"
```
```python
# test_abc.py
def test_bar(snapshot): assert snapshot == "abc"
```
```

pytest==7.1.1

With the above code, if I run `pytest test_a.py`, the snapshot from `test_abc.py` is flagged as unused:

echo 'def test_foo(snapshot): assert snapshot == "a"' > test_a.py
echo 'def test_bar(snapshot): assert snapshot == "abc"' > test_abc.py

# create snapshots
pytest --snapshot-update  # 2 snapshots generated.
pytest  # 2 snapshots passed.

# running test_abc.py: all okay
pytest test_abc.py --snapshot-details  # 1 snapshot passed.

# running test_a.py: unused snapshots (BUG)
pytest test_a.py --snapshot-details  # Unused test_bar (__snapshots__/test_abc.ambr)
pytest test_a.py --snapshot-details --snapshot-update  # Deleted test_bar (__snapshots__/test_abc.ambr)
```

**Expected behavior**

When running pytest against a single/subset of files, snapshots from other files shouldn't be considered unused.
