PortalUtil.getPlidFromFriendlyURL(companyId, friendlyURL) is possible to return 0 even if given parameters are valid.
For example, when 'friendlyURL' is '\web\mysite', the method will try to get the Layout with '\web\guest\1' to return plid.
The problem is, '\1' seems only valid when the first created page in the group exists. So it's not always safe to try '\1'.

Steps to reproduce:

1) Add a community
2) Add 2 page to created community
3) Delete first created page
4) Call PortalUtil.getPlidFromFriendlyURL(PortalInstances.getCompanyId(request), "/web/your-community")
