Improvements to debugger

[joelpramos]

• Previously when the debugger stopped with an error in a step, whenever a step was evaluated via "Debug Console" in VS Studio the previous exception throwable was always returned confusing the user about his activites;
• Added a simple version of using conditional breakpoints in VS Code. The condition needs to evaluate to a boolean.
  • if it evaluates for something else other than a boolean the debugger will not use the condition and it'll just stop on the breakpoint like
  • Only simple Karate expressions are accepted (no keywords, just boolean conditions e.g. variable == 'val') or JS functions in the format of function() { return true; }
  • For convenience of syntax highlighting, added support to include the Cucumber prefix but keywords (e.g. match) will NOT work. Few examples of using this:
    a) code in the Karate boolean condition directly
    
    b) boolean condition with the star ('*') prefix for fancy colors:
    
    c) condition in JS
    
    d) go nuts with your JS ...
    

Tips:

• Right click on the left of the line number for the option 'Conditional Breakpoint'
  
• Use Shift+Enter to add new lines in that debugger window/swimlane in VS Code.
• Press Enter to confirm/apply the condition

Improvements of using the "Debug Console" after errors.

Previously after an error occurs in a step and the debugger stops, if you tried to do anything in the Debug Console (e.g. '* print 'test') the step would be executed but the previous error message from the context would be returned. Not anymore.
