- clean up error messages
- default errorMessage to ''
- Test for no GlAlert in default case

"please try again" was removed due to the
irrelevence of it for this particular error

Previously was trying to avoid an eslint error, but the
error was since resolved and hence the code could be
simplified.

Added unit and "integration" tests for
createDesignDetailFlash util function

Design Destroyer is used both on the Issue page,
and in the "design detail" page, and errors need to be
flashed in each respective place.

Previously, Design Destroyer flashed errors within it.
Now, this has been removed and parent components
are responsible for flashing errors

Error handler added for design query in Apollo,
and error message consolidated

New function "createDesignDetailFlash" replaces
"createFlash" wherever it was used to create a flash within the
"design detail" view of design management

Wraps `createFlash` to create the flash within the
design-detail container
