core: Missing member in alias if updated

Some of my network seemed incomplete: by looking at Firewall: Diagnostics: pfTables I can see members are missing.

Steps to reproduce:

1. Go to Firewall: Aliases: View.
2. Create the following network aliases:
   • TEST_LAN_1 = 192.168.1.0/24
   • TEST_LAN_2 = 192.168.2.0/24
   • TEST_LAN_3 = 192.168.3.0/24
   • TEST_LAN_4 = 192.168.4.0/24
   • TEST_LAN_5 = 192.168.5.0/24
   • TEST_LAN_x = TEST_LAN_1, TEST_LAN_2, TEST_LAN_3
3. Update TEST_LAN_x by adding the following two members:
   • TEST_LAN_4
   • TEST_LAN_5
4. Apply alias changes with the Apply changes button.
5. Alias listing page should show contains:

Name	Type	Description	Values
TEST_LAN_1	Network(s)		192.168.1.0/24
TEST_LAN_2	Network(s)		192.168.2.0/24
TEST_LAN_3	Network(s)		192.168.3.0/24
TEST_LAN_4	Network(s)		192.168.4.0/24
TEST_LAN_5	Network(s)		192.168.5.0/24
TEST_LAN_x	Network(s)		TEST_LAN_1, TEST_LAN_2, TEST_LAN_3, TEST_LAN_4, TEST_LAN_5

1. Go to Firewall: Diagnostics: pfTables page.
2. Select TEST_LAN_x

Expected result:

Table should be:

IP Address
192.168.1.0/24	🗑️
192.168.2.0/24	🗑️
192.168.3.0/24	🗑️
192.168.4.0/24	🗑️ ️
192.168.5.0/24	🗑️

Actual result:

Table is:

IP Address
192.168.1.0/24	🗑️
192.168.2.0/24	🗑️
192.168.3.0/24	🗑️

Extra step:

1. Go to Firewall: Aliases: View.
2. Rename alias TEST_LAN_x to TEST_LAN_x_bis.
3. Apply alias changes with the Apply changes button.
4. Go to Firewall: Diagnostics: pfTables page.

Table for TEST_LAN_x is still:

IP Address
192.168.1.0/24	🗑️
192.168.2.0/24	🗑️
192.168.3.0/24	🗑️

Table for (the newly created entry) TEST_LAN_x_bis is:

IP Address
192.168.1.0/24	🗑️
192.168.2.0/24	🗑️
192.168.3.0/24	🗑️
192.168.4.0/24	🗑️ ️
192.168.5.0/24	🗑️
