Error when importing large number of injects

[marckto-filigran]

When importing injects, if the xls contains a large number of injects: it will only import 100 injects max.
Also, some injects are duplicated...

Reproducing steps:

1. Import the following xls
   testchronogramme.xls
2. Choose mapper "test générique"
3. You get duplicated injects, and in my case only half the injects imported but as doublons

Hi @marckto-filigran 👋

After digging a bit the bug along with @Dimfacion, we found out that this issue has a workaround.
-You don't see the injects after importing but you do if you refresh the page (bug)
-The injects don't appear over a 100 because of a pagination bug
-The doublons appeared because you might have done the import twice ? It works on our side

Here is the issue we'll tackle, so i'll close this one 🙏
