Bug #97975 Import from CSV should open last directory

Description:
Workbench should remember the directory from which files are being imported into the Inserts tab of the Modeling tools.

How to repeat:
1. Open MySQL Workbench
2. Open Modeling.
3. Create a model or open an existing one.
4. Create or click on a specific table to bring up the table editor below.
5. Click "Inserts" on the bottom tab-strip. 
6. Ensure there are some rows of data.
7. Next to "Export/Import," first click to Export the table.
8. The default folder opened in the file explorer is the last one used for exporting, or the user's home directory if none.
9. Edit the exported file.
10. Click Import to open the "Import Recordset from CSV File."
11. The default directory opened is the user's home directory.
12. Navigate to where the file is that you want to import.
13. Select the file and import it.
14. Repeat steps 9-13 as desired.

Suggested fix:
Step 11 should be changed so that the default is the last directory used for import.  If none, the last directory used for export.  If none, the user's home directory.
Then step 12 would not be needed.

Hello Ben Towne,

Thank you for the reasonable feature request!
