Change reified triple to triple term

[pchampin]

According to the description of the test, this should be a triple term, not a reified triple...

I believe the test here is intentional and correct, but the description might need changes.

AFAICS, the standalone form <<(:s1 :p true)>> . is not allowed by the Turtle spec, while <<:s1 :p true>> . is.
The former is not a full triple, while the latter is (in its expanded form).

My bad, my fix is indeed an invalid turtle file :-( I'll make a suggestion to fix it.

I believe the test here is intentional and correct, but the description might need changes.

Note that there are two similar tests:

• turtle12-6: Turtle 1.2 - reified triple with keyword object
• turtle12-8: Turtle 1.2 - triple term with keyword object

The two input files of those tests are identical, which is a copy-paste error IMO. While this file is correct for turtle12-6, it should be adapted for turtle12-8.

Indeed, since we already have turtle12-6, this change looks good to me.

It is "reifiying triple" so several descriptions need updating.
