Wrong portal alias is created when adding new languages

[daguiler]

Description of bug

When a second language is added to DNN, 2 localized portal aliases are added along: 1 for the default language, and 1 for the second language.
These 2 new portal aliases are created by taking the first portal alias and adding language segments. This is ok when the first portal alias is also the primary portal alias, but should not be the case when a portal alias other than the first one is the primary one.

Steps to reproduce

1. Install 9.4.4 and inspect Languages and Site Aliases:

Languages:

Culture	Enabled
English (United States) **	Yes

Site Aliases:

Alias	Browser	Primary
platform-9-4-4-25776.dnndev.me	Normal	Yes

2. Add a new primary alias:

Alias	Browser	Primary
platform-9-4-4-25776.dnndev.me	Normal
dnn-944.dnndev.me	Normal	Yes

3. Add a second language:

Culture	Enabled
English (United States) **	Yes
Afrikaans (Suid-Afrika)	Yes

4. Inspect the site aliases again:

Alias	Browser	Primary
platform-9-4-4-25776.dnndev.me	Normal
dnn-944.dnndev.me	Normal	Yes
platform-9-4-4-25776.dnndev.me/en-us	Normal	Yes
platform-9-4-4-25776.dnndev.me/af-za	Normal	Yes

Current behavior

The 2 new portal aliases were created after the first portal alias.

Expected behavior

The 2 new portal aliases should have been created after the primary portal alias, like this:

Alias	Browser	Primary
platform-9-4-4-25776.dnndev.me	Normal
dnn-944.dnndev.me	Normal	Yes
dnn-944.dnndev.me/en-us	Normal	Yes
dnn-944.dnndev.me/af-za	Normal	Yes
