Shared header files not written in bulk-create mode if first table create fails #23
Description
The shared files that are written once per bulk-create session (e.g. CompiledPerfectHash.h, CompiledPerfectHash.props, etc) are not written if the first table in a bulk-create command fails. (Or rather, they are created, but the table create failure inadvertently deletes these files as well as the table-specific files.)
