Lost messages when contexts are used

[akimd]

I have just discovered that this project is no longer maintained. I'll therefore work to migrate to the recommended system.

However, for the record, when there are two identical msgids, one with a context and the other without, the one without context is ignored.

It is unique_translations that drops the missing translations.

mk = ->(ctx, id, str) {
    res = GetPomo::Translation.new
    res.msgctxt = ctx if ctx
    res.msgid = id
    res.msgstr = str
    res
}

translations = [
    mk.(nil, 'Amount', 'Montant'),
    mk.('Invoice', 'Amount', 'Montant'),
]
GetPomo.unique_translations(translations)

=>

[#<GetPomo::Translation:0x00007ffb57cac218
  @msgctxt="Invoice",
  @msgid="Amount",
  @msgstr="Montant">]
