bug: tool invocation fails after /load

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue

### Operating system

GNU/Linux x86_64

### Expected behaviour

After using a tool and then using /save and /load to restore the state of the conversation, I can use the tool again.

### Actual behaviour

After using a tool and then using /save and /load to restore the state of the conversation, I can no longer use the tool.

### Steps to reproduce

# High-level idea

1. In a Q session, use a simple custom mcp tool, then `/save` the state of the conversation.
2. In another Q session, `/load` that state and use the same simple custom mcp tool again.

This seems to cause the error:

```txt
Tool validation failed:
The tool, "foobar___get_word_of_the_day" is supplied with incorrect name
```

# Example

## Simple MCP tool

In a simple MCP server `foobar` we have:

```python
@mcp.tool()
def get_word_of_the_day() -> str:
"""Takes no input and returns today's Word of the Day."""
return "The word of the day is: photography."
```

## First Q session
```txt
🤖 You are chatting with claude-4-sonnet

> How much is 10 times 10?
10 times 10 equals 100.

> What is the word of the day?

🛠️ Using tool: get_word_of_the_day from mcp server foobar
⋮
● Running get_word_of_the_day with the param:
⋮ {
⋮ "arguments": {},
⋮ "name": "get_word_of_the_day"
⋮ }
Allow this action? Use 't' to trust (always allow) this tool for the session. [y/n/t]:

The word of the day is: photography.

> /save state_photography.json

✔ Exported conversation state to state_photography.json

> /quit
```

## Second Q session
```txt
🤖 You are chatting with claude-4-sonnet

> /load state_photography.json

✔ Imported conversation state from state_photography.json

> What is the word of the day?

Tool validation failed:
The tool, "foobar___get_word_of_the_day" is supplied with incorrect name
Let me try again with the correct tool name:
