Properly support related list navigation.

Properly support related list navigation.

Navigation from the "Repository Analyzer -> Package Scans ->
Dependencies" related table wasn't working because the primary key for
related tables wasn't being set properly. This commit fixes the
problem.

* src/main/java/org/glom/web/server/ConfiguredDocument.java: Don't use
getListLayoutGroup() to create the LayoutItemPortal DTO. This method
doesn't set the primary key properly for related list tables.
* src/main/java/org/glom/web/server/database/DBAccess.java: Add table
name parameter to getPrimaryKeyLayoutItemField(). This makes the method
useful for getting the primary key for list view tables and for related
list tables.
* src/main/java/org/glom/web/server/database/ListDBAccess.java:
* src/main/java/org/glom/web/server/database/ListViewDBAccess.java:
Move code to set the primary key for the table from the abstract
ListDBAccess class to ListViewDBAccess as it's only correct for list
view tables.
* src/main/java/org/glom/web/server/database/RelatedListDBAccess.java:
Properly add primary key to related list tables.
