Unit test on single file is converted to integration test
### Apache NetBeans version

Apache NetBeans 14

### What happened

I noticed that my Netesta plugin does not work anymore with Netbeans 14.
Each time it tries to apply `ActionProvider.COMMAND_TEST_SINGLE`, the action is replaced by the new `COMMAND_INTEGRATION_TEST_SINGLE`.

### How to reproduce

I use Netesta plugin to automatically trigger unit tests on a single file

### Did this work correctly in an earlier version?

Apache NetBeans 13

### Operating System

Ubuntu

### JDK

1.8, 11, 17 & 18

### Apache NetBeans packaging

Apache NetBeans binary zip

### Anything else

I have done some debugging, so I can tell where the problem occurs. 

In the class `DefaultReplaceTokenProvider`, in the method `isIntegrationTestTarget`, the variable `targetFiles` can be also empty (and not only `null`)

In this case, the `allMatch` method of the stream return `true` whereas there are no files.
