Fix javascript client with IE11

1) use minimal angular app available here:
https://jira.nuxeo.com/secure/attachment/54983/test-js.tar%20%282%29.gz

2) try to access the application, while developer tools opened under IE11

3) result is the same as :
https://jira.nuxeo.com/secure/attachment/54982/IEvsChrome.png

4) this points to the following call in nuxeo.js :
https://jira.nuxeo.com/secure/attachment/54913/js_1.0.x.png

This does not work with 1.0.x but works fine with 0.25.0.
Also, supported version of Chrome 46 and Firefox 38ESR are not affected.
