Clear output on rerun

[netcoding87]

Clear and concise description of the problem

When running vitest in watch mode, the output gets not cleared before rerunning the test. This leads to the problem, that on scrolling it is often hard to find the "border" where the latest run started :/

Suggested solution

Clean the output before rerun
