`bit update`: check whether update is needed

yermulnik commented 4 years ago

Describe the bug bit update doesn't check its version of the installed binary but re-downloads itself over again

To Reproduce Run bit update and watch it updating from latest to latest version.

Expected behavior bit update compares installed version to latest and downloads update only when needed.

This may be due to the symlink issue since bit update does/should check.

This was a bug related to when versions are something without a "v" in SemVer
