CSV import format validation

[AMDG2]

When trying to import CSV from clipboard I have error message. When I check the log I see this:

{
	"reqId":"xxxxx",
	"level":3,
	"time":"2019-12-03T15:33:05+00:00",
	"remoteAddr":"xxxxx",
	"user":"xxxxx",
	"app":"PHP",
	"method":"POST",
	"url":"\/index.php\/apps\/analytics\/data\/importCSV",
	"message":"sizeof(): Parameter must be an array or an object that implements Countable at \/path\/to\/nextcloud\/apps\/analytics\/lib\/Controller\/DataLoadController.php#150",
	"userAgent":"Mozilla\/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko\/20100101 Firefox\/70.0",
	"version":"17.0.1.1"
}

I tried with these CSVs:

A;B;B
1;2;3
3;4;5
6;7;8

A,B,B
1,2,3
3,4,5
6,7,8

May be this is not what is expected?

Hello,
welcome do Data Analytics.

Please try it without the header. just

1,2,3
3,4,5
6,7,8

I am still working on hardening/errorhandling here (including better messages).
does it work?

[AMDG2]

It works with the suggested CSV.

However I have to double check because it may be related to the fact that I disabled the uBlock origin (most of the assets are getting blocked due to analytics in the name).

Ok, I can confirm that the suggested CSV works. I will open another issue for the uBlock problem.
