Increase ivy-flx-limit for improved fuzzy behavior

The default setting of 200 is too low for common use-cases like
`describe-function`, `describe-variable` or `counsel-projectile`.

This has a performance impact, but it's barely noticeable on a fast
machine. If performance is not acceptable, set `ivy-flx-limit` lower or
consider disabling the `+fuzzy` feature entirely.
