Mirrored jar stop transfering essentia when source is full

[drayath]

Version: gadomancy-1.7.10-1.0.7.3

Reproduction

Place a thaumcraft Mirrored Jar (A), link and place Mirrored Jar (B).
As essentia is added to jar A it is shared between the 2 jar.
Allow both jars to completely fill.
Drain some essence from jar B.

Expect: essence to be split between 2 jars
Actual: Jar A remains full, jar B remains empty with no essence transfer occurring.

If you manually (with phial) remove some essence from jar A everything start working again until jar a completely refills again.

May be the same cause as #92

looks like #91 would fix this.
