test: aligned pluginName with naming for functions

[travi]

based on

semantic-release/lib/plugins/normalize.js

Line 17 in 78ea3ba

const pluginName = name.pluginName ? name.pluginName : isFunction(name) ? `[Function: ${name.name}]` : name;

, i think this test was wrong before and this change fixes it. i think i read the logic correctly, but the fact that this test has been the other way for a long time makes my confidence low that this is the right change, so i could really use a sanity check on this one.

for #2543

Change looks good to me
