Revising companyId to local scope property

- Using appropriate camel case to change it to `companyId`
- `companyId` now local scope as it didn't need two-way binding
- Updated test HTML to apply `company-id` attribute instead of `local` and provided a value
- Updated bower to use latest common-style version
- Updated demo to correct usage of `company-id` attribute
