Do not use {{request_token}} insert tag

[ameotoko]

{{request_token}} insert tag is deprecated in Contao 4.13 and produces wrong value.

[ameotoko]

I did not yet fixed iso_collection_default.html5 and iso_collection_favorites.html5 because I'm not sure which class is responsible for it.

Isotope (currently) still supports Contao 4.9, so we have to continue to use its features even if they are deprecated. But thanks for the PR, this will give us a head-start once we can fix this 😊

[ameotoko]

This change does not conflict with Contao 4.9. Did you try it on Isotope Demo?

and produces wrong value.

The request token insert tag should not produce a wrong value, that would be a bug in Contao.

[fritzmg]

Other than that the changes lgtm and should be compatible with Contao 4.9 anyway.

The request token insert tag should not produce a wrong value, that would be a bug in Contao.

I think I meant that I was getting "CSRF token is invalid" message all the time. The value is not necessarily wrong.

[fritzmg]

But if that happens only with the insert tag, it would still be a bug somewhere? Changing it to the service should make no difference.

[ameotoko]

TBH I cannot reproduce it now either. May be the reason lied elsewhere, and I got A LOT fixed and updated in my Isotope app since this was opened. So probably you can disregard produces wrong value remark, but since the insert tag is deprecated anyway, merging this would still be a move forward, WDYT?

[aschempp]

@ameotoko could we rebase this to 2.9 and use the getDefaultTokenValue then?

Thank you @ameotoko
