Fix search saving, and add some unit tests

Also:

- Return an object from `Zotero.Search.prototype.getConditions()`
  instead of an array.
- Add support function `getPromiseError(promise)` to return the error
  thrown from a chain of promises, or false if none. (We could make an
  `assert.throwsAsync()`, but this allows testing of various properties
  such as `.name`, which even the built-in `assert.throws()` can't
  test.)
- Clarify some search save errors
