Ruby Syntax Error Checker Hangs Test Runner

[spmartinapl]

The Test Runner fails to open on certain Ruby syntax errors, specifically missing end curly braces in puts statements that include variables.

puts "#{foo" for example.

Steps to reproduce the behavior

1. Create a test group which has a puts statement syntax error like below (missing curly end brace)
   puts "#{foo
2. Load Test Runner.
3. It should fail to open and hang on the below screen. The syntax error, however, is not reported.
   

Expected behavior
For comparison, vanilla ruby fails in the follow manner when I try to run a script with the same syntax error. See below for the test script.

#!/usr/bin/ruby
def syntax_test
    foo = 12
    puts "Hello"
    puts "Hello #{foo"
    puts "Done"
end
sytanx_test

See below for the syntax error thrown.

Environment

• OS: Ubuntu v18.04.3 LTS
• COSMOS v4.4.0

@spmartinapl You can test my fix by going to line 523 of lib/cosmos/tools/script_runner/script_runner_frame.rb and adding:
eval("lambda { #{text} }")

To find the file click Help->About and clicking "Open COSMOS Gem Code"
