Using description as MessageID makes goi18n fail

[voroskoi]

Hi,

First of all: Thank You very much for this amazing package.

I have the following active.en.toml file:

description = "Description"

[comment]
one = "Comment"
other = "Comments"
zero = "No Comment"

If I run goi18n.exe merge .\active.en.toml against it I get the following error message:

failed to load message file .\active.en.toml: expected value for key "comment" be a string but got map[string]interface {}{"one":"Comment", "other":"Comments", "zero":"No Comment"}

Changing 'desctiption' in the first line to anything else makes the problem go away.
Calling LoadMessageFile method also fails with this input.

I have tried to convert the toml file to yaml too, but does not help.

I am using github.com/nicksnyder/go-i18n/v2 v2.1.2.

Using other gives the same result.
