Subject: [PATCH] fix($compile): backport to 1.2 of workaround for IE11
 MutationObserver

Backport #11796 to 1.2 branch.
IE11 MutationObserver breaks consecutive text nodes into several text nodes.
This patch merges consecutive text nodes into a single node before looking for interpolations.
Also had to modify npm-shrinkwrap.json because i@0.3.2 was unpublished from npm.

Closes #11781
