`dolt table import -c` with excel file with sheet named "test" does not work

If you try to create a new table named `test` by importing an excel file with a sheet named "test" using `dolt table import -c test [file].xlsx` it fails with

```
Rows Processed: 8, Additions: 8, Modifications: 0, Had No Effect: 0

A bad row was encountered while moving data.
Bad Row:
invalid column: league_id
These can be ignored using the '--continue'
```
If you change the sheet to a name that is not "test" the import is successful. Creating tables named "test" with other types of files (like csv) works too 🤷‍♀️
