Fix issues with MeasureManager

[macumber]

• [x] Add loading tab to discourage selecting another measure which arguments for first measure are being computed (this can take a long time in failure case).
• [x] Catch all std::exceptions instead of just RubyExceptions which prevents crash. Fixes #656
• [ ] Display more informative message in case of "Failed to Infer Measure Name". Related to #716
• [ ] Fix "Do you want to reset Measure Manager settings" #717
