Cleaner check that either `ID` or `WebEnv` (but not both) set #50

This relates to #48 ,

At the moment we check this in a hacky way in make_entrez_query. It's probably better to have a function in base.r that handles this.

The only combination that actualy get's used is ID or WebEnv, so we can hard-code that option
