[Bug] statictoc template not compatible with _enablesearch

**Describe the bug**
Using "default" and "statictoc" templates, with [_enablesearch](https://dotnet.github.io/docfx/reference/docfx-json-reference.html#_enablesearch) results in the search box being shown but not showing search results when used.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a site with `docfx init`
2. Replace the templates list in docfx.json with `default` and `statictoc`
3. Add a `GlobalMetadata` section to `build` with `"_enableSearch": "true"`
4. Build the website
5. Open index.html in Chrome
6. Type a term into the search box and press enter to submit

**Expected behavior**
Search results are presented for the term entered

**Actual behaviour**
Nothing happens
