Spaces in bus alias member definitions no longer separate members
# Description
From the eeschema docs: "As a shortcut, you can type or paste in a list of signals and/or buses separated by spaces, and they will all be added to the alias definition."
I used the tokenization when typing in a bus alias member and noticed that it does not work anymore. Further inspection shows:
| Tokenization | 9.0.7 | 9.0.8 | 10.0.1-rc1 |
| ------------ | ----- | ----- | -------- |
| When Typing | ✅ | ❌ | ❌ |
| When Pasting | ❌ | ❌ | ❌ |
Possibly the docs mean "edit an alias member and paste a string while editing the cell" rather than "paste the string into the table (not editing the cell, no cursor)". I found that the latter does not work. The former is no different than typing the list of members.
# Steps to reproduce
1. Launch eeschema and open schematics setup.
2. Navigate to "Bus Alias Definitions".
3. Add any alias.
4. Add a member and type "SDA SCL <Enter>". Notice that a single member "SDA SCL" is added rather than "SDA" and "SCL" separately.
