Unordered list items added when editing templates

When editing a global template that contains macros, an unordered list item <ul> is added for each macro placeholder (variable) that the template contains. This causes the template macros to break when used to create a page.

Steps to replicate:
1. Edit a global template (eg. Meeting Notes). Save without making any changes.
2. Edit the template again and use the Source Editor to inspect the template code. An <ul> item is created at the very top of the template for each macro that it contains. Save.
3. Attempt to create a page with the newly edited template. The macros do not render.
