feat(path): Keypath should parse if sub path contains spaces.

[exoego]

Closes #532 (and its original #502)

I believe "hierarchical key containing space 0x20" like nested.Hello World should be OK, since non-hierarchical key like Hello {0} can contain space.

vue-i18n/test/unit/basic.test.js

Lines 92 to 97 in 70eedb1

	it('should return replaced string if available', () => {
	assert.strictEqual(
	i18n.t('Hello {0}', ['kazupon']),
	'Hello kazupon'
	)
	})
