Conduit textures contain hidden pixels with alpha 0

Relates to MC-245930 and MC-278377.

The bug

There are several pixels in the images in textures/entity/conduit which are at an alpha level of 0, but nonetheless have color data.

How to reproduce

The example ImageMagick command in MC-278377 can be adapted for use on these texture files to reveal these pixels.

Expected results

All pixels not actually used in these textures would be zero-opacity black.

Actual results

There is remaining color data.

How to fix

Fixed versions of these textures are attached under their original names; also attached are versions with alpha removed, revealing these hidden pixels.
