fix(ByDisplayValue): improve warning message

[xgbuils]

What:

• Improve warning message in ByDisplayValue queries: "with the value:" -> "with the display value:"
• Update snapshots for element not found error message.
• Ensure that multiple elements error message is changed as expected (No test failed when message was changed).

Why:

As said in #442, the current message is quite misleading.

Checklist:

• Documentation added to the
  docs site (N/A)
• I've prepared a PR for types targeting
  DefinitelyTyped (N/A)
• Tests
• Ready to be merged
