Dacpac Extract crashes SqlToolsService if invalid version is used

[kevcunnane]

1. Open dacpac wizard and choose extract
2. Set version to 1.0.0.0abcd
3. Click Next and kick off the wizard

Actual:
Get error SQL Tools Service component exited unexpectedly. Please restart Azure Data Studio.

Expected:
a) Validation on page blocks going Next until a valid version is defined
b) the SqlToolsService code needs an overall try/catch to avoid crashing if anything goes wrong with the dacpac export. This breaks the entire app
