uncommitted changes ignored, but branch name still appended

```
plugins {
id("pl.allegro.tech.build.axion-release") version "1.21.3"
}

scmVersion {
localOnly.set(true)
useHighestVersion.set(true)
versionCreator.set(PredefinedVersionCreator.VERSION_WITH_BRANCH.versionCreator)
tag {
prefix.set("")
}
}
```

With this config active, I checked out the branch `next` (anything not `main`) whose most recent commit is tagged with `8.0.0-alpha.3`. Running `currentVersion` returns `8.0.0-alpha.3` as expected.

When adding `ignoreUncommittedChanges.set(false)` without committing, running `currentVersion` returns `8.0.1-next-SNAPSHOT` - also as expected due to the uncommitted config change.

Now changing this to `ignoreUncommittedChanges.set(true)` still without committing changes the outcome of `currentVersion` to `8.0.0-alpha.3-next`. I would rather expect the initial output without the branch name appended.

The SNAPSHOT appender is not active because it ignores the uncommitted changes, and so should the branch name appender.

Haven't checked how other version creators behave in that case
