Do not inform user during precompilation

The current approach seems to have multiple disadvantages:
- If the user only got `TensorOperatoins.jl` as a indirect dependency, the information seems to be completely useless
- It's untypical to give information about a package during precompilation. That's what Readmes, docstrings or similar things are for
- The user can't deactivate it. If I read the code correctly, even setting the preference to false would print the warning again

So until a better solution is found, I think it makes sense to deactivate the precompile output.
