[YAQL] MuranoPL raised exception without pointing to a particular line

[Alexey Khivin]

If error ocurrs in the "initialization" method then developer will see something like

2015-06-25 12:25:45 - [yaql.exceptions.YaqlExecutionException]: Unable to run find

it is hard to understand where exactly this error occurs if there are several "find" calls in the application and it would be nice for developer to see line number or whole trace

[Ekaterina Chernova (efedorova)]

I suggest to:

1) wait for integration with yaql 1.0
2) run same app (with error) on new murano

see if error occurred again

The problem is only for initialize method that get called during object model deserialization and was fixed in Liberty. Need to investigate how much efforts it will require to implement the same for the Kilo (there is no commit to backport, it was done as a part of much bigger refactoring). Most likely it's not worth it
