Error when document starts with example, before the test #57
Description
I have a Markdown doc that contains an example before the Knit tests begin
Here's an example of a tuple definition in TypeScript:
```typescript
type StringNumberPair = [str: string, num: number];
```
<!--- CLEAR -->
<!--- TEST_NAME TuplesTest -->
<!--- INCLUDE .*\.kt
-->
```kotlin
fun main() {
// ...
}
```
> You can get the full code [here](./code/example/example-tuple-01.kt).
```typescript
export type SimpleTypes = [
aString: string,
anInt: number,
aDouble: number | null,
bool: boolean,
privateMember: string,
];
```
<!--- TEST -->When I run ./gradlew knit I get an error:
Previous test was not emitted with TEST
Cause
I believe this is caused by the CLEAR directive clearing codeLines, but not testLines
Lines 293 to 298 in bd8e272
Context
- Gradle 8.3
- Knit 0.4.0
