i18n._ function removes unrecognized macros

[nmoinvaz]

Describe the bug
i18n._ removes macros that are unrecognized. This prevents programs that also parse macros in strings from handling them after Lingui loads them.

To Reproduce
Using the following code:

i18n._("code {hello}")

The string returned is code .

Expected behavior
It should return code {hello} because no values object was passed to i18n._.

Alternatives ideas

1. Perhaps there is a callback that can be triggered when it encounters a macro it doesn't recognize?
2. Or an option that can be enabled for this behavior?
3. Or another function that does not process macros but can get the locale string.

Worse case, it looks like according to PEG, it should be possible using a literal to bypass parsing.

i18n._("code '{hello}'")

Translates to "code {hello}"

Fixed, starting from next version

i18n._("code '{hello}'")

Should work
