Make Wasp more robust (fewer wasp clean calls)

[sodic]

This is a very, very high-level issue, but...

Most of our troubleshooting begins by telling the user: Did you run wasp clean?

This indicates low trust in wasp start and Wasp's handling of runtime changes. We should strive to reach a point where the suggestion of running wasp clean is as unreasonable as TS devs suggesting "Did you try deleting the dist folder."

This is, of course, a lot of non-obvious work, but the issue pops out all the time, and I had to document the it somewhere :)

It was caused by reinstalling dependencies.
