Fuzzy search in completions is not working correctly

## Compiler version
3.7.0

## Minimized code


```Scala
object M:
  def scalaVersion(scalaVersion0: String): String =
    sa@@
```

## Output

```scala
saferExceptions
```

## Expectation

scalaVersion + scalaVersion0 as it does for e.g 
```Scala
object M:
  def scalaVersion(scalaVersion0: String): String =
    sl@@
```
