In the process of using babel, I found that when `browserslistConfigFile` is not set to `false` and browsersList is not set, babel will still call the related methods of browsersList and caniuse-lite, I think this is unnecessary, Because browsers is an empty array at this time, it is a truthy value, so I modified the judgment condition to not handle it when it is undefined or an empty array.

…tion is called via side effects.
