Delete columns sometimes doesn't work anymore

[rdstern]

I am using the merged version of R-Instat

@Vitalis95 and @lilyclements I am pretty sure this bug has followed the merging of pull request #8398.

I read in the usual survey and immediately tried to delete the columns as shown below. It doesn't work anymore:
It should be easy to fix as I explain below:

.
I suggest the problem is that deleting a column, now checks and deletes the corresponding key columns. This data frame doesn't have a key. If I add a key, then the delete works fine. The code needs to cope with the situation where there is no key.

Ah yes, a very good point, and quite a big bug to introduce too! My mistake, I have fixed it here #8416 @rdstern

@lilyclements and @rdstern
Hello I am having this same issue when using what i think is the most updated version through visual studio. It happens when i try to delete or rename a column.
If this has been fixed in a version that i am not using my apologies.

@rachelkg yes I noticed this too, this should all be fixed in #8422 and so should be sorted in the most recent version. Can you check and confirm this for you? If it is ok now, I will close this PR :)

@lilyclements I can now delete columns successfully but when i try to rename I get this error message.
Which is interesting as it looks like it is different from what i got last time.

@rachelkg a very good point, sorry about that. I've now fixed it in #8433
