🐛 Fix too small JSON payload triggering md with high ratio

[Ousret]

Close #58~

To reproduce:

from charset_normalizer import from_bytes

results = from_bytes(b"{}").best()

Expected encoding = 'ASCII'; Got 'UTF-16 (Variant)'.

Why does this happen?

Because the first pass consists of assessing the "mess/chaos" ratio, and one of the detection plugins was unadjusted for a small JSON payload.
