Issue Title

Provide a general summary of the issue in the Title above,
Something descriptive and related to the issue + Mod Version in [].
Example Custom GT++ Alveary Frame Blocks do not work [v1.5.0-alpha]

Expected Behavior

If you're describing a bug, tell us what you expect should happen.
If you're suggesting a change/improvement, tell us how it should/could work.

• Put GT++ cell (specifically Sulfuric Coal Tar Oil Cell in my case) into EnderIO Pressurized Tank to empty fluid. Expect fluid to go into tank and for empty cell to return.

• Right click GT++ cell (same cell) on EnderIO Pressurized Tank to empty fluid. Expect fluid to go into tank and for empty cell to stay in my hand.

Current Behavior

If describing a bug, tell us what happens instead of the expected behavior.
If suggesting a change/improvement, explain the difference from current behavior.

• Either right clicking with a GT++ (specifically Coal Tar Oil Cell in my case) or putting the cell into EnderIO Pressurized Tank causes the cell to empty the contents correctly but then the empty cell disappears.

• (I know you will say blah booooo get outta here but adding it for more flavor :P) This same behavior is exhibited in the EC2 Fluid Terminal.

• GT++ cells (specifically Coal Tar Oil Cell in my case) work fine in GT++ tanks.

Possible Solution

Not obligatory, but suggest a fix/reason for the bug,
or ideas how to implement the addition or change.
No idea but I'm hoping that whatever is causing it is basically the same thing for everything.

Steps to Reproduce (for bugs)

Provide a link to a live example, or an unambiguous set of steps to
reproduce this bug. Include code to reproduce, if relevant.

1. React Sulfuric Acid Cell x1 with Coal Tar Oil Cell x1 in HV Chemical Reactor to get Sulfuric Coal Tar Oil Cell x2.
   2a. Put Sulfuric Acid Cell x2 into EnderIO Pressurized Fluid Tank GUI and cell disappeared in my case.
   2b. Right click Sulfuric Acid Cell x1 (stack of 2 but only right clicking once) on EnderIO Pressurized Fluid Tank and cell disappeared in my case.

Context
