Dev server is broken in 0.99 when using the Multilingual Multihost mode

[freud14]

The dev mode for Multilingual Multihost seems to be broken in 0.99. It is not broken in 0.98. Here are the steps to reproduce.

• Create a new site:

  hugo new site quickstart

• Edit config.toml:

  defaultContentLanguage = 'en'
  [languages]
    [languages.en]
      baseURL = 'https://example.com'
      title = 'My blog'
      weight = 1
    [languages.fr]
      baseURL = 'https://example.fr'
      title = 'Mon blogue'
      weight = 2

• Run:

  hugo server

  resulting in:

  panic: runtime error: index out of range [1] with length 1
  
  goroutine 1 [running]:

If you remove the baseURL fields, the hugo server command seems to work as expected.

What version of Hugo are you using (hugo version)?

$ hugo version
hugo v0.99.0-1de333e7a3fc863672ec6d6cd53ba66dbcdd2305+extended linux/amd64 BuildDate=2022-05-16T08:10:56Z VendorInfo=gohugoio

Does this issue reproduce with the latest release?

It does with 0.99. The problem is not there in 0.98.

Happening to me as well with my repo, which built without issues with v0.98. I (and Netlify too) can build my site correctly running hugo even with v0.99 though, so the problem is only with hugo server.
