fix: macros generates invalid ICU message for nested selects

[Nodge]

Babel macros generates invalid ICU messages for nested select/plural.

Example source code:

select('id', {
  value: "male",
  male: select({
    value: true,
    true: "He invites guests",
    other: "He does not invite guests"
  }),
  female: `She is ${gender}`,
  other: `They is ${gender}`
});

Expected message:

{0, select, male {{1, select, true {He invites guests} other {He does not invite guests}}} female {She is {gender}} other {They is {gender}}}

Actual message (missing brackets after male):

{0, select, male {1, select, true {He invites guests} other {He does not invite guests}} female {She is {gender}} other {They is {gender}}}

lingui complie throws error for this message:

Error: Can't parse message. Please check correct syntax: "{0, select, male {1, select, true {He invites guests} other {He does not invite guests}} female {She is {gender}} other {They is {gender}}}"
