Bugfix with multiple specs producing null values in reporter results

When using multiple nested specs, due using only one variable `i` for iteration the suites array produced in the json report contains`undefined` values.

Before fix:
http://extensa.pl/projekty/github/jsreporter/indexMulti.html
````
> jasmine.getJSReport()
Object {suites: Array[4], durationSec: 0.045, passed: true}
> jasmine.getJSReport().suites
[Object, undefined × 2, Object]
````

After fix:
http://extensa.pl/projekty/github/jsreporter/indexMultiFix.html
````
> jasmine.getJSReport()
Object {suites: Array[2], durationSec: 0.042, passed: true}
````

Also, I've updated jasmine submodule in the example to current version 1.3.1.
