Add test for NH-2893

Test requires explicit execution due to use of Sybase SQL Anywhere with a customised driver. Unfortunately none the current CI databases have drivers where UseNamedPrefixInSql returns false. This is required to reproduce the issue. Databases reported with the issue are Pervasive PSQL, IBM DB2 and Informix - all with UseNamedPrefixInSql = false.
