[TIMOB-24736] Fix issue in minification of code

[ewanharris]

JIRA: https://jira.appcelerator.org/browse/TIMOB-24736

This is a potential fix for the above, I dont think it is the right fix however as we will not be minifying code fully as we did before with uglify

The bug TIMOB-24736 refers to is in Alloy, not Titanium Mobile or node-titanium-sdk.

@cb1kenobi, this PR turns babel-plugin-transform-inline-consecutive-adds off and prevents minifying step to fold assignment into object declaration.

var test = { a: 0, b:0, c:0 };
test.b = 1;

minified to:

var test={a:0,b:0,c:0,b:1};
